1 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
3 * exception.c (arch_handle_exception): exclude runtime invoke
4 wrapper from the stack trace
6 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
7 (mono_thread_start_cb): save an additional LMF at thread start
9 2003-01-16 Martin Baulig <martin@ximian.com>
11 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
12 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
13 and the LinuxThreads port doesn't allow you to override the handler.
14 [FIXME: This avoids an assertion failure on startup, but there's
15 still an issue with thread termination.]
17 2003-01-16 Martin Baulig <martin@ximian.com>
19 * debug.c: Use the mono/io-layer functions here instead of gthread.
21 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
23 * jit.c (mono_jit_compile_method): make sure runtime_init is called
24 (mono_analyze_stack): make sure runtime_init is called
26 2003-01-14 Martin Baulig <martin@ximian.com>
28 * debug.c (debugger_update_symbol_file_table): Moved all the
29 functionality into debugger_update_symbol_file_table_internal();
30 the latter one will be called from the background thread while
31 already owning the lock. This'll allow us to step into
32 debugger_update_symbol_file_table() in the debugger and debug it.
34 2003-01-14 Martin Baulig <martin@ximian.com>
36 * Makefile.am: Link against gthread.
38 * jit.c: After realizing that mono-mutex doesn't work either
39 because it doesn't support recursive mutexes on FreeBSD, rewrote
40 the whole thread stuff to use gthread. This seems to fix this
41 weird deadlock in the debugger as well.
43 2003-01-12 Alp Toker <alp@atoker.com>
45 * exception.c: Typo fix: insinde -> inside
47 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
49 * exception.c (ves_icall_get_frame_info): skip one more frame and also
50 MONO_WRAPPER_RUNTIME_INVOKE wrappers
51 (x86_unwind_native_frame): disable unnecessary assertion
53 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
55 * exception.c (ves_icall_get_frame_info): fix bug 36382
57 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
59 * jit.c: handle wrapper_data in NEWOBJ/CALL.
61 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
63 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
65 2003-01-06 Martin Baulig <martin@ximian.com>
67 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
69 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
70 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
72 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
74 * debug.c: Move must_send_finished var declaration out of #if win32
75 block (this fixes the build on win32)
77 2003-01-05 Martin Baulig <martin@ximian.com>
79 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
80 this is used when we're running inside the Mono Debugger
81 (mono_debugger_wait): Put the waiting code into a function of its own.
83 * mono.c (main): Call mono_debugger_jit_exec() instead of
84 mono_jit_exec() if we're running inside the Mono Debugger.
86 2003-01-05 Martin Baulig <martin@ximian.com>
88 * debug.h (MonoDebugFormat): Added
89 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
90 we're running inside the Mono Debugger prior to the args parsing.
92 2003-01-04 Martin Baulig <martin@ximian.com>
94 * debug.c (release_symbol_file_table): Only call this if we're
95 actually modifying the symbol tables.
96 (mono_debug_open): Always set the `mono_debugger_class_init_func'
97 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
99 2003-01-03 Martin Baulig <martin@ximian.com>
101 * debug.c: Disable the mono debugger stuff on Windows.
103 2003-01-03 Martin Baulig <martin@ximian.com>
105 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
106 function. This is called from the breakpoint trampoline to signal
107 the debugger and wait until it has reload the symbol tables.
109 * trampoline.c (get_breakpoint_trampoline): Call the new
110 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
111 trampoline just before the breakpoint.
113 2002-12-31 Martin Baulig <martin@ximian.com>
115 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
116 field to point to the MonoGlobalSymbolTable.
118 2002-12-30 Martin Baulig <martin@ximian.com>
120 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
121 This variable now specifies that the symbol tables have been
122 modified after the last notification has been send. The debugger
123 uses this flag to check whether it needs to reload the symbol
125 (debugger_compile_method): Just send a notification to the
126 debugger, but don't set the modified flag. It may or may not be
127 set when the debugger gets the notification - depending on whether
128 the JIT compilation added a new method to the symbol tables.
130 2002-12-30 Martin Baulig <martin@ximian.com>
132 * debug.c (debugger_compile_method): This is a wrapper around
133 mono_compile_method() which always sends a notification to the
136 2002-12-30 Martin Baulig <martin@ximian.com>
138 * debug.c: Reload the symbol file table before sending the
139 notification event to the debugger.
140 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
142 2002-12-31 Martin Baulig <martin@ximian.com>
144 * debug.c: Propertly lock everything and avoid race conditions.
145 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
147 2002-12-31 Duncan Mak <duncan@ximian.com>
149 * debug.c (initialize_debugger_support): Fix build error by
150 declaring ret at the top of the function.
152 2002-12-30 Martin Baulig <martin@ximian.com>
154 * debug.c: When running under the mono debugger, create a special
155 debugger thread; always protect the symbol tables with a mutex.
157 2002-12-28 Martin Baulig <martin@ximian.com>
159 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
160 incremented each time one of the symbol tables is modified.
162 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
164 * jit.c: fix LDELEMA implementation here as well.
166 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
168 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
170 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
172 * jit.c: query the thread abort signal from the runtime.
174 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
176 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
178 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
180 * jit.c (mono_analyze_stack): call the utility function
181 mono_field_from_token to avoid code duplication.
183 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
185 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
187 * x86.brg (stmt): POP floating point stack correctly
189 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
191 * emit-x86.c (arch_emit_prologue): don't save caller saved
194 * exception.c (x86_unwind_native_frame): support exceptions inside
195 native code using gcc generated exception tables (-fexception).
197 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
199 * exception.c: include some code from Zoltan Varga, but modified
202 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
204 * exception.c: massive code cleanups. The code is still
205 architecture dependent, but it should be now possible to reuse the
206 complex parts for other architecture.
208 2002-11-15 Dick Porter <dick@ximian.com>
210 * jit.c: Pass the attach callback to mono_runtime_init().
212 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
214 * jit.c: display the domain name in trace output.
216 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
218 * x86.brg (reg): fix bug #2721
220 * jit.c (mono_runtime_install_handlers): impl.
222 2002-10-17 Martin Baulig <martin@gnome.org>
224 * debug.c (mono_debug_add_method): Make this actually work if we don't
225 have any lifetime information.
227 2002-10-15 Martin Baulig <martin@gnome.org>
229 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
231 * debug.c (generate_line_number): Small fix to make this actually
232 work for more complex things.
234 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
236 * x86.brg (freg): use fprem instead of fprem1
238 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
240 * jit.c (ves_array_element_address): added check for out of range index
241 (mono_analyze_stack): added fix for bug #31654
243 2002-10-01 Martin Baulig <martin@gnome.org>
245 * debug.c: Don't create an .il file for the dynamic symbol file.
247 2002-10-01 Martin Baulig <martin@gnome.org>
249 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
251 2002-09-27 Martin Baulig <martin@gnome.org>
253 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
255 2002-09-27 Dick Porter <dick@ximian.com>
257 * mono.c: Tell glib what the program name is, by passing it the
258 name of the managed file we're executing
260 2002-09-26 Martin Baulig <martin@gnome.org>
262 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
263 trampoline into the vtable, also use it for non-virtual methods,
264 remove the breakpoint when done.
266 2002-09-26 Martin Baulig <martin@gnome.org>
268 * debug.c (debug_load_method_lines): Block SIGCHLD while running
271 2002-09-26 Martin Baulig <martin@gnome.org>
273 * debug.c: Reworked the whole debugging stuff. We have now one
274 single `mono_debug_handle' which keeps a hashtable of
275 `AssemblyDebugInfo's (which may have different debugging formats).
276 The AssemblyDebugInfo is now created when the assembly is loaded,
277 but never when adding a class/type.
279 * mono.c: Initialize debugging stuff after corlib and the assembly
282 2002-09-25 Martin Baulig <martin@gnome.org>
284 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
285 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
287 (DebugMethodInfo): Removed `line_numbers'.
289 * debug.c: Reworked the line number generation; we're now using
290 the MonoDebugLineNumberEntry try for all debugging formats. This
291 type also includes the line number and IL offset, this allows the
292 JIT to produce better line number info: we only emit line number
293 information for source lines which actually have code.
295 2002-09-25 Martin Baulig <martin@gnome.org>
297 * debug.h: Removed external declaration of all functions which
298 should only be called from the Mono Debugger and also made them
299 static. Since the debugger gets their address from the
300 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
303 2002-09-25 Martin Baulig <martin@gnome.org>
305 Improved breakpoint support, we can now dynamically insert and
306 remove breakpoints at runtime and when called from withing the
307 Mono Debugger, we're using a special breakpoint trampoline.
309 * debug.h (mono_method_has_breakpoint): New method to check
310 whether to insert a breakpoint for a method.
311 (mono_insert_breakpoint): New method to insert a breakpoint.
312 (mono_insert_breakpoint_full): New method to insert a breakpoint,
313 takes a MonoMethodDesc.
314 (mono_remove_breakpoint): New method to remove a breakpoint.
316 * debug.c (mono_debugger_insert_breakpoint): New function for the
317 debugger. Should only be called from the debugger.
318 (mono_debugger_remove_breakpoint): Likewise.
320 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
322 * trampoline.c (get_breakpoint_trampoline): New static function to
323 create a special breakpoint trampoline for the debugger.
324 (x86_magic_trampoline): If we're running inside the Mono Debugger
325 and a breakpoint was requested for the method, generate a special
326 breakpoint trampoline.
328 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
329 to insert a breakpoint.
330 (mono_debug_last_breakpoint_address): Removed.
331 (match_debug_method): Removed, use mono_method_has_breakpoint().
333 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
335 * jit.c: reorder mono_runtime_cleanup () call since it needs the
336 engine still fully working.
338 2002-09-24 Martin Baulig <martin@gnome.org>
340 * debug.c (mono_debug_open): When we're invoked from inside the
341 Mono Debugger, set mono_debugger_class_init_func (exported in
342 metadata/class.c) to mono_add_type().
343 (mono_add_type): Call mono_debug_symfile_add_type().
345 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
347 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
348 Run finalize on domain cleanup.
349 * mono.c: call setlocale ().
350 * trampoline.c: clearer error message for invalid trampoline.
352 2002-09-21 Martin Baulig <martin@gnome.org>
354 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
355 instead of writing a byte blob.
356 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
357 (mono_debug_add_method): Incrementally add the new method to the symbol
360 * exception.c (arch_handle_exception): If we have debugging support,
361 call mono_debugger_update_symbol_file_table () as well.
363 2002-09-20 Martin Baulig <martin@gnome.org>
365 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
366 the size of the variable.
368 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
370 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
371 iterations if we visit blocks in reverse order.
373 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
375 * jit.c (mono_analyze_stack): cleaup of the array code
377 * exception.c: added patch from Julio Merno to fix bug #30048
379 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
381 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
383 * x86.brg (LDELEMA): use x86_lea
385 2002-09-06 Martin Baulig <martin@gnome.org>
387 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
388 If you were getting random crashes when using the JIT with debugging
389 turned on, this fixes it.
391 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
393 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
395 2002-09-05 Martin Baulig <martin@gnome.org>
397 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
398 which is read by the debugger.
400 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
402 * Makefile.am: link libmono directly into mono. Use a ld script
403 to reduce exported symbols.
405 2002-09-03 Martin Baulig <martin@gnome.org>
407 * debug.c (free_method_info): Make this actually work.
409 2002-09-03 Martin Baulig <martin@gnome.org>
411 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
412 * debug-dwarf2-plus.c: Removed.
414 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
415 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
416 `mono_symfile' to `symfile'.
418 * debug.c (mono_debug_open): Replaced the assembly argument with a
419 file name argument; you can now call this before loading the assembly.
420 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
421 we now use MonoSymbolFileLineNumberEntry's and a separate address array
422 instead; splitted out all MonoSymbolFileLineNumberEntry code into
423 debug_generate_il_offsets() and debug_update_il_offsets().
424 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
425 created when reading the symbol file or from debug_load_method_lines().
426 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
428 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
429 looking up an address.
431 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
433 * mono.c (main): Initialize debugging before loading the first assembly.
435 2002-08-28 Dick Porter <dick@ximian.com>
437 * mono.c: mono_set_rootdir() doesnt take any args now
439 * Makefile.am: Export HOST_CC for w32 builds
441 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
443 * jit.c (mono_store_tree): only allocate vars if really necessary
445 2002-08-27 Martin Baulig <martin@gnome.org>
447 * debug.c: The mono symbol file is installed together with the assembly
448 it belongs to and it's used on a per-image basis.
450 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
452 * mono.c: don't use the cil-coff header outside of the loader.
454 2002-08-27 Martin Baulig <martin@gnome.org>
456 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
457 to use global variables for this since they're stored in a core file.
458 (mono_debugger_symbol_file_table_generation): New global variable.
459 (mono_debugger_symbol_file_table): New global variable.
460 (mono_debugger_update_symbol_file_table): New global function to update
461 the symbol file table.
463 2002-08-27 Martin Baulig <martin@gnome.org>
465 * trampoline.c (mono_generic_trampoline_code): New global variable.
466 (arch_create_jit_trampoline): Use the new global variable to store the
467 generic trampoline code instead of using a static one. This allows the
468 debugger to access this variable to check whether a method is a trampoline.
470 * debug.h (mono_generic_trampoline_code): Added external declaration.
472 2002-08-27 Martin Baulig <martin@gnome.org>
474 * debug.c (MonoDebugHandle): Moved the method hash into the
475 AssemblyDebugInfo struct since we need to use a separate hash for each
478 * debug.c: Added special undocumented command line argument to create a
479 symbol file for IL files on-the-fly. In this case, we also need to create
480 the IL files and parse them.
481 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
483 2002-08-26 Martin Baulig <martin@gnome.org>
485 * debug.c (mono_debugger_internal_free_symbol_files): New function.
486 (mono_debugger_internal_symbol_files_changed): New global variable.
488 2002-08-24 Martin Baulig <martin@gnome.org>
490 * debug.c (mono_debugger_internal_get_symbol_files): New function.
492 2002-08-24 Martin Baulig <martin@gnome.org>
494 * debug.c (mono_debug_write_symbols): Added support for the new
497 * mono.c (main): The `--debug' argument now knows about a new
498 debugging format `mono' which will be used to display source lines
501 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
502 which will be used when displaying backtraces. It reads a new
505 2002-08-23 Martin Baulig <martin@gnome.org>
507 * jit.c (match_debug_method): Don't include runtime invoke methods
510 * mono.c (main): Accept `Main' as argument to --break to insert a
511 breakpoint on the application's main method.
513 2002-08-23 Martin Baulig <martin@gnome.org>
515 * debug-dwarf2.c (dwarf2_write_class_field): Don't include any static fields.
517 2002-08-21 Dietmar Maurer <dietmar@ximian.com>
519 * exception.c (arch_handle_exception): don't set stack_trace to
520 null (so that it contains the full trace even when we rethrow the
523 2002-08-19 Nick Drochak <ndrochak@gol.com>
525 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
526 the algebraic form we are using. This also eliminated a silly overflow
527 of the intermediate result that was causing troubles.
529 2002-08-16 Nick Drochak <ndrochak@gol.com>
531 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
534 2002-08-15 Nick Drochak <ndrochak@gol.com>
536 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
537 will not fit in 64 bits. Fixes bug #27375.
539 Wed Aug 14 17:31:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
541 * exception.c: updates for API changes in metadata/.
543 2002-08-13 Dietmar Maurer <dietmar@ximian.com>
545 * jit.c (mono_jit_init): use ((gpointer)-1) as end_of_stack
546 address for the main thread.
548 2002-08-12 Dietmar Maurer <dietmar@ximian.com>
550 * jit.c (mono_analyze_stack): added support for Thread::Abort ()
552 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
554 * exception.c (arch_handle_exception): simply return and let the
555 libpthread/kernel restore the context. This should work on recent
556 versions of linuxthreads.
558 * jit.c (mono_runtime_install_handlers): switch back to use
559 sigaction from libpthreads. As long as this does not make problems
560 we should use this instead of syscall.
562 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
564 * jit.c: removed the createdelegate icall
565 (mono_analyze_stack): special case Array::Address()
567 2002-08-06 Dietmar Maurer <dietmar@ximian.com>
569 * emit-x86.c (arch_emit_prologue): make the call to
570 mono_get_lmf_addr relocatable.
571 (arch_jit_compile_cfg): do not waste memory
572 (arch_jit_compile_cfg): use a mempool to store native code. This
573 improves locality of code.
575 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
577 * jit.c (mono_analyze_stack): impl. CEE_MONO_RETOBJ
579 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
581 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
582 than one page, it's necessary to allocate memory incrementally,

1004 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1005 file for all assemblies. Currently, the JIT doesn't put all methods
1006 from a single assembly into a continuous region of memory. We were
1007 previously creating valid DWARF 2 files for this, but unfortunately
1008 GDB's symbol tables get messed up when it reads more than one such file.

1106 * exception.c (arch_handle_exception): EIP now points to the call
1107 instruction, not to the instruction after the call. This fixes the

1478 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1479 numbers, we still need to generate the IL offsets here. Emit line numbers
1480 for `prologue_end_offset' (the first line of actual code) and
1481 `epilogue_begin_offset' (the line of the method's closing brace).
1482 Don't crash if cfg->bblocks [i].forest is NULL.
1483 (mono_debug_add_method): Don't crash if we don't have line numbers.
1484 Initialize the newly added fields.
1486 * debug-stabs.c: Record first and last line, emit filename info at the

1489 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1490 emit line number info for the first and last line.
1492 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1556 2002-03-23 Martin Baulig <martin@gnome.org>
1558 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1559 to do it before the X86_CMP.

1643 parent classes of a class type.
1645 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1646 since GDB doesn't like Java very much.
1648 2002-03-16 Martin Baulig <martin@gnome.org>
1650 * debug-dwarf2.c: Added support for enums.
1652 2002-03-15 Martin Baulig <martin@gnome.org>

1673 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1675 (mono_debug_open_file): Added MonoDebugFormat argument.
1676 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1677 this function from GDB. It's now safe to call this function multiple times;
1678 it'll always write a complete debugging file.
1680 * debug.c: Splitted this file into a general part which remains in this file
1681 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1682 All public functions now call a corresponding format specific function.
1684 * debug.c: The following changes are private to debug.c:
1685 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1686 (record_line_number, debug_generate_method_lines): New private functions.
1687 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1688 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1689 mono_debug_open_assembly_dwarf2).
1690 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1691 now safe to call this function multiple times.
1692 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1693 returns an unique index for this type. It's used to ensure that we only write
1694 each class once to the debugging file.
1695 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1696 data structure, but don't directly write to the debugging file. This is done
1697 later from mono_debug_write_assembly().
1699 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1700 debugging output. Call mono_debug_close() on cleanup if necessary.
1702 2002-03-14 Martin Baulig <martin@gnome.org>
1704 * debug-private.h: New private header file.
1706 * debug-stabs.c: Added the stabs type generation stuff which was
1707 previously in debug.c.
1709 * debug-dwarf.c: Started to implement type support. We're currently
1710 only writing this most basic types to the dwarf file, but this will
1713 2002-03-13 Martin Baulig <martin@gnome.org>
1715 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1716 debugging code. They're now in CVS, but not yet used anywhere.
1718 2002-03-11 Dietmar Maurer <dietmar@ximian.com>

2319 and x86.brg. Added more documentation. code cleanup.
2321 2001-09-25 Dietmar Maurer <dietmar@ximian.com>
2323 * x86.brg: we now have different types of addresses: ADDR_L for local
2324 values, ADDR_A for arguments and ADDR_G for global addresses. We
2325 also use LDIND_XX token to load values from a specific address
2326 instead of LDLOC/STLOC.
2328 * testjit.c: use the new adressing scheme everywhere:
2329 LDIND _XX (ADDR_X), and STIND_XX (ADDR_X, tree)

2363 * x86.brg: added basic support for long
2365 * testjit.c (mono_compile_method): implemented POP
2367 2001-09-19 Miguel de Icaza <miguel@ximian.com>
2369 * testjit.c (usage): Added a couple of more usage options.
2371 2001-09-19 Dietmar Maurer <dietmar@ximian.com>

2434 * emit-x86.c: only save/restore callee saved registers if they are
2437 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2439 (mono_compile_method): changed the tree for mothod calls
2446 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2448 * x86.brg: Use Unix assembly syntax.
2450 * emit-x86.c: support code, should be moved
